Run a 14 generation search on this breeding. Will get some interesting results. Bass' Cleo bitch was a black dog. I showed a solid black bitch years back that was owned by Louis Miles. That bitch was a straight Red Boy x Cleo bitch. Louis Mile's Bouncer was a full sibling brother to Red Boy and was a tiger brindle colored dog.
A dog man that lived not far from Bass, had a yard of young dogs bred off Bass' Red Boy x Cleo. Some were black, some where brindle/red brindle and some red /red nose dogs. I no longer remember his name. I might be wrong, thinking maybe Rowell's Fancy was obtained from this dog man. Rowell's Fancy was a red /red nose female dog. Cheers
